I'm configuring a 3560 switch port for port security using Sticky, from my reading, we can't use sticky mac for voice vlan, and we need to set the maximum mac-addresses to min 3 since two mac-addresses will be used by Cisco ip phone and the third for my laptop.
My question, i connected a Cisco ip phone to the switch port and my laptop connected to the ip phone, only one mac address is appeared at the running config for voice vlan and one for my laptop, so why Cisco talks that we need to define two mac addresses for IP phone?
this was a bug. It has been fixed in 12.2(25)SEE images and later . The bug id is CSCea80105 . After the fix of this bug , you should not have to configure 3 mac addresses and 2 mac-addresses should work fine in this env.
We actually encountered another bug in 12.2(35)SE1 and 12.2(37)SE in which case the 2 macs per interafce ( 1 for vvlan and 1 for data vlan) did not work. That bug got resolved in 12.2(40)SE . the bug id is CSCsj47067. In short , you will need 12.2(40)SE if you want to have 2 mac-addresses maximum per interface ( 1 for voice and 1 for data ).
